WISR (680 AM) is a commercial radio station that is licensed to Butler, Pennsylvania. The station was the first to go on the air in Butler County, doing so on September 26, 1941. The station was the last to be granted a broadcast license before the FCC halted the licensing of any additional stations until after World War II.

It has always broadcast on AM 680 with a maximum power output of 250 Watts, non-directional. WISR had operated as a daytime-only station until it was granted limited nighttime power in the late 1980s.

The station has a construction permit for an FM translator (W298CW) that would allow it to operate at 107.5 MHz. The permit was granted January 25, 2018. The FM translator officially signed on air September 28, 2021, making WISR available on both the AM and FM bands, and was licensed effective October 15, 2021.

After more than two decades of ownership under the Butler County Radio Network, WISR was sold to Pittsburgh Radio Partners on September 2, 2022. After less than two months, St. Barnabas Broadcasting announced that it would acquire WISR and its affiliate stations from Pittsburgh Radio Partners. The purchase was consummated on February 14, 2023, at a price of $2.55 million.
